To all whom may concern Be it known that I lVI'LLL-Ui ll. IiliLLin-i. a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of Calitorniu have invented neu and useful Improvements in rakes v which the following is a symciiicati-on.

This invention relates to a vehicle brake and pertains particularly to a vehicle brake suitable to be mounted upon the Ford type of our.

it is the principal object of this invention to provide cars of the Ford type with band brakes Which act upon drums of ened diameter and are/adapted to he substituted' for the internal expanding brakes in common use.

Another object is to provide a bond brake u h u drum of enlarged diameter which iii-1y be mounted in combination with the brake housing in use upon a Ford car so that no alteration of the parts involved need be made or special dust shields provided.

Another object is to provide a special broke supporting spider W13 ich ina y be readily applied to the vehicle axle and will support the brake band at various points around its periphery in a, floating and resilient manner.

Another object is to provide a'hrulre band actuating mechanism which is simple in its construction. and may be readily adjusted.

Another object is to provide means incorporated Within the hralre adjusting mecha nism whereby universal reloti on between the parts will he ofi'orded,

lit is a 'f ".rther obyect to provide :i band brake construction which is composed of few parts and W110i! may be readily mounted as a substitute for the present rmnding brake used upon the rear axle of Ford cars.

@ther objects Will appear hereinafter. I

The invention is illustrated in illl. ucconr penying drawings in which:

Figure 1 'is a View in side elevation of the brake drum and its hand as mounted upon a vehicle axl and as seen looking outwardly toward the wheel. I

Fig. 2 is a View in vertical section as seen on the line 2-2 of Fig. l. and with parts broken away.

Fig. 3 is a View in vertical section through the central bend suspension member as particularly illustrated in Fig. 1.

Referring to the drawings more particu- 'the spider arm and a. i ssnerl il lu :ly, 1.0 indicates the rear driving axle of on automobile and snowing the axle rotatably mounted Within an axle housing .11. Theouter end of the axle is secured in a suitable manner Within a. Wheel hub 12 provided with e. circular bolting flange 13 against which -schicle spokes l-l are secured by means of bolts The axle housing as commonly constructed, is iorined uiti circular flange members 16 which are disposed at rightengles to the oil" nterence of the housing and normally utilized as a means for inclosing 1e open end of brake drums which, in this construction, have eliininoted. All of the foregoing mentioned parts those which are standard upon cars to which this invention relates and are used Without alteration.

The brake mechanism here provided consists of u. drum member 1? formed with an end portion 18 around the outer edge of which an annular Wall 19 is made. The Hill 19 is fitted with an inwardly extending flange portion 26 which lies paras the end portion 18 and ternii Mes zidgcccnt the outer periphery of member to with Which the axle housing is provided. The drum, as described, is secured to the vehicle wheel bolts which pass tl'irough the bolting flange 13 and are held by nuts 21 t irough the end wall 18 of the drum. A spider 2:2 is bolted upon the flange 16 of the axle housing by a bolt 23 which was originally used in connection with the old brake. This holtp through a horizontally disposed Sold urui ivl extends rearwardly m the drum and is engaged 1c pass through an opening i the s' and issecured by on enlz l ed fla ge porn 27 to u circular flexible steel 3 i by suitable rivets. A coil sp is p mound the pin and excl 2: force bets held adjacent the end oi the pin by pin 31. This spring acts to dry and thebrake bend attached-t away from the brake drum band lies. 1111113 and 3S oi. til nienilier extend at right an arm and upon opposite sures tnereor These urins bend at their ends and overhung the brake drum and are mlupted to receive pins 34: and 35 nhich are secured to the brake band and hold the band. in its outermost position by means of coiled springs 36 which act against Washers 37.

the circnlz r flange nut 43 is mounted upon the end of an adjusting bolt 44 which is pivotally connected within the looped end 45 of the brake band. It will thus be seen thatby means of the wing-nut 43 the band may be adjustably drawn around the periphery of the brake drum 17 and cause its frictionlining 46 to bear thereupon.

The brake actuating lever 38 is mounted to rotate at its center and is fixedly secured to a brake shaft 47 which is in turn rotated by means of a lever arm 48 operatively connected to a connecting link 49 which leads to a suitable foot pedal or hand lever. By

' the rotation of the shaft 47 the brake lever is moved in the direction indicatedby the arrow at in Fig. 1 and when so rotated will draw the terminating ends of the brake band together and thus cause the friction lining 46 to bear forcibly against the outer periphery of the brake drum 17.

In applying the brake mechanism here shown to a vehicle of the Ford type it is first necessary to remove the wheel and brake drum with which it is equipped and place the drum 17 upon the wheel in lieu of the original drum. The wheel is then remounted upon the axle and secured by a nut 50 which engages the end of the axle spindle. When the wheel is in position it will allow the flange portion 20 of the brake drum to register with the periphery of theflange 16 and thereby prevent dust and dirt from collecting within the drum. The brake spider 22 is now secured in position upon the flange 1G by means of the bolt 23. Theband brake is mounted upon the spider in the resilient manner afforded by the coiled springs 29 and 36. When the band is connected at its terminating ends to the brake operating mechanism it is in its complete assembled position. v

In operating the band brake, the connecting link 49 is drawn and the lever arm 38 is swung, as indicated by the arrow, this action drawing the brake band tightly around the drum and compressing the suspension springs 29 and 36, which normally maintain the band in a floating condition.

It will thus be seen that a band brake is here provided as a. substitute for a brake of smaller diameter and power and that the brake here 'described'and illustrated may be with the hub and spokes and span the space 4 to the housing flange, said brake drum being larger in diameter than the housing flange and there being an inwardly extending drum flange registering with the housing flange, a brake band for the drum, a spider secured to the housing flange and yieldingly sup porting the brake band, and means for op erating the brake band.

'I claim:

1. A brake attachment for a wheel construction; said wheel construction having an axle housing, a circular housing flange extending from the end of the axle housing, an axle in the axle housing, a wheel hub upon the axle against the end of the axle housing, and spokes extendingfrom the hub and I spaced from the housing flange; said attachment comprising a brake drum adapted to be mountedrigid with the hub and spokes and span the space to the housing flange, said brake drum being larger. in diameter than the housing flange and there being an inwardly'extending drum flange registering with the housing flange, a brake band for the drum, a spider secured to the housing flange and yieldingly supporting the brake band, and means for operating the brake band. i

2. A brake attachment for a wheel construction; said wheel constructionhaving an axle housing, a circular housing flange extending from the end of the axle housing, an axle in'the axle housing, a wheel hub upon the axle against the end of the axle housing, and spokes extending from the hub and spaced from the housing flange; said attachment comprising a brake drum adapted to be mounted rigid witlrthe hub and spokes and span the space to'the housing flange, said brake drum being larger in diameter than the housing flange and therev being an inwardly extending drum flange registering with the housing flange, and a brakev band for the drum.

In testimony whereof I have signed my name to this specification.
